This document discusses using HyperForm simulation software to calculate formability and tonnage requirements for developing a sheet metal forming process for manufacturing a sleeve component. It describes simulating the multi-stage forming process, including cupping, calibration, and cutting steps. The simulation predicts metal flow, risks of defects, and required press .There are a few significant advantages to coin bending sheet metal, the first of which are high repeatability, precision, and the ability to reduce the inside radius to as small as desired. During the Coining process the material is put under enough pressure that the punch tip penetrates the material at the bottom of the bend and it begins to .Calculate the required force to bend a piece of sheet metal using the wipe bending method. In this process, the sheet is held between a wipe die and clamp pad, while a punch presses against the edge of the sheet. The calculated tonnage can be used for the selection of a machine, such as a press brake, to perform the bending operation.

Actual section is not a true arc of a circle but a segmented line, formed by several straight lines.
Abstract— Sheet metal forming is widely used in automotive and aerospace sector. . This paper is based on the calculation of different part use in deep drawing process such as blank diameter, draw ratio, draw force, clearance, machine tonnage etc. Mathews Kaonga [5] discussed about the forming processes such as punching, blanking and . For many years I have used the following formula to calculate the forming force that would be required to complete a bend: Forming tonnage per inch = (575 × Material thickness2)/Die opening/12. From there, the answer would be factored for material type, length of bend, and method of forming.
To find the tonnage required for a hydraulic press intended to deform a metal sheet, use the press’s tonnage per square inch requirement. For thin aluminum sheets, assume a requirement of 10 tons per square inch. With a pressing area of 30 square inches, the press tonnage needed is 10 tons/sq in × 30 sq in = 300 tons. . In the sheet metal .
